Our History

Advanced Sealing and Supply Company was incorporated in 1988 with the inspiration of Bill Clouse and Alan Stubblefield; who envisioned an independent company focused on bringing the advantages of advanced technologies to their customers.

The initial focus was on packings, gaskets and expansion joints for major industrial accounts. But the commitment to bringing changes to their customers would bring big changes to Advanced Sealing, as well!

1988 – Advanced Sealing and Supply Company was formed with an emphasis on cutting-edge technologies.

1989 – Advanced Sealing introduced the first mechanical packing that allowed the refineries to meet the stringent new valve emission standards of Rule 1173. This development set a new standard of performance that would take five years for competitors to meet.

1996 – Advanced Sealing expanded our hose fabrication line as we began manufacturing metal hose assemblies. This strong emphasis continues to this day, and we now have 5 code-certified welders to B31.1, B31.3 and ASME Section IX.

2004 – 2004 marked a turning point for Advanced Sealing, as we transitioned from a purely “distribution” model to a “manufacturing” model. This was done in order to ensure our customers a reliable supply of quality products made to our stringent standards. As part of that transition, Terry Subia, an expert in refinery products and services, was hired to coordinate our refinery services.

2006 – Advanced Sealing entered the fastener business. In line with our manufacturing emphasis, we purchased multiple state-of-the-art computerized self-indexing saws, chamfer machines and nutting tables. We established our own stamp, and brought in generous inventories of threaded rod in popular grades, as well as standard fasteners. This commitment to inventory and equipment allowed us to enhance our cost saving opportunities to the refineries through “kitting” the gaskets, lubricants and fasteners for maintenance work on pressure vessels, heat exchangers, reactors, etc. This saves our customers on initial purchase price, simplifies support logistics and staging requirements in a turnaround, and reduces emergency buys during planned maintenance outages.
